Of all the intersecting genes, ZNF503 (57), S100A12 (57), RNASE1 (58), LHFPL3 (59), TRPM4 (60), and UCHL1 (61) have been confirmed to be associated with depression, and, among these six genes, only UCHL1 (62) and S100A12 (63) are involved in the progression of pulmonary fibrosis. Here, S100A12 is linked to major depressive disorder.
